ok jus got a drag three kit for free basically from a buddy, and thought might as well throw it on my h22 ek. my question is i only plan on running 5-7psi maybe 9 at the most and i noticed the drag kit doesnt come with any injectors. so would the jdm ob1 stock injectors i have now be ok i think there 310cc's or should i upgrade to 450 etc? wutever you think would be a good idea to have let me know. i want this motor and turbo to last me a few years.
